Infection: Infection is the most common cause of dental implant failure. It can occur at any time during the implant process, from surgery to the healing phase to long after the implant has been placed. Bacteria can enter the implant site through the gums or through a small opening in the implant itself. Infection can cause inflammation and bone loss, which can lead to implant failure.
Peri-implantitis: Peri-implantitis is a type of gum disease that affects the gums around dental implants.
Insufficient bone support: Dental implants need to have enough bone support to be successful. If the jawbone is too thin or weak, the implant may not be able to fuse with the bone properly (osseointegration). This can lead to implant failure, especially if the implant is placed under too much stress.
Implant overload: Overloading occurs when too much force is placed on the implant. This can happen from bruxism (teeth grinding), clenching, or chewing hard foods. Overloading can damage the bone around the implant and lead to implant failure.
Other factors that can increase the risk of dental implant failure include:
Smoking
Diabetes
Poor oral hygiene
Certain medications, such as bisphosphonates and corticosteroids
Medical conditions that affect the immune system, such as HIV/AIDS and leukemia.
If you are considering dental implants, it is important to talk to your dentist about your risk factors.
